    Quoted from soren:

    But, the datasheet does not mention the minimum voltage requirement (oddly enough).

    Looks like it's 2.0 volts:

    In terms of shelf life, I had a bunch of 15 year old N.O.S CR2032 batteries sitting on the shelf in not exactly ideal conditions.

    A lot of "KTS" branded batteries went flat a long time ago. The Sonys and Panasonics still have 3 volts, so too the Toshibas but the Toshibas look stained like they've dry leaked. Also one Maxell left still reads/looks good.
    I still have all the flat batteries from this stash, I should probably pull them out to get more details.
